Knight Capital's Trading Floor

As speculation swirls that Knight Capital Group could go of out business after reportedly losing more than $400 million Aug. 1 when a software error misfired a program trade, causing mayhem in 148 listed stocks, regulators have the firm under a microscope. Advanced Trading takes you behind the scenes to view Knight's cavernous trading floor in Jersey City, N.J., where the firm's electronic trading operations and traders are based. Taken two years after it was built, the photos show how the floor is structured and include close-ups of the technology used on specific desks.
